2017 WORLD Champion Jason Doyle is the latest rider to be named for the Neil Middleditch Testimonial at Poole on August 31.
Doyle made over 100 appearances as a Pirate between 2005 and 2011, but has not appeared at Wimborne Road for three years.
Middleditch said: “I’m so pleased to welcome Jason to my meeting and thrilled that he has accepted the invitation.
“I have such great respect for his achievements, and I can’t forget how he helped us to an Elite League title in 2011.
“Of course, now he has moved on to be a truly World Class rider and a deserved World Champion. He remains a force in the top echelons of World Speedway and I’m proud to call him a great friend.”
